I don't get the reasoning for naming the Grandfather part in the "Grandfather Paradox"
First...
A man builds a time machine.
He goes back in time to met his Grandfather as a young man, before he got married and had children.
He gets into an argument with his Grandfather, and kills him.
Since his Grandfather never had children, the Time Traveler can't be born.
Since the Time Traveler was never born, then he can't build a time machine...
...and without the Time Machine, the (non-existant) Time Traveler can't go back in time.
The Grandfather is not killed.
The Grandson, builds a time machine...
Now...
Why couldn't this be called: The "Father paradox", or the "Mother Paradox", or even the "Great Grandfather Paradox"?
Wouldn't killing all of THESE people before THEY had children, result in the Time Traveler not being born too?
So, why was it named the "Grandfather" Paradox?
